The niper robot issit bombshelter casing, I think of putting at fushan garden to move continuously around there? The tall height to be like Cisco or Certis. If like m1, when robot at area = information(that passerbys if read), like "any info for this passerby?" To prompt(if they stand long at robot), or if they just stand for some time if I not asleep I can c anyway(if looking). Means it depends on passerby, even if uniform type(means even if stranger to me).
